Climate Common Sense is not a sceptical site but a non-believer's site .Global warming and cooling are natural phenomena and carbon dioxide is a lovely gas vital to plant growth. Global Warming has stopped and Climate Change ( I call it Weather) is the new manufactured bogeyman. This website will present a realist view on the Climate Change debate.

Clouds create positive/negative feedback for global warming

When Ken Gregory wrote an article titled "Clouds have made fools of climate modelers" it provoked a Pavlovian response from the climate scam's guard dog John Cook who immediately produced a rebuttal stating that : So while clouds remain a significant uncertainty and more research is needed on this subject, the evidence is building that clouds will probably cause the planet to warm even further, and are very unlikely to offset a significant amount of human-caused global warming.

On the contrary it seems evidence is building that John Cook does not know what he is talking about.

The University of Auckland has had its head in the clouds, and its conclusion is they are getting lower.

The university looked at ten years of data from Nasa's terra telescope to discover the average cloud height decresed by 1% over the past decade.

The telescope showed fewer clouds were occuring at higher altitudes.

Researchers believe a significant reduction in cloud height would lead to reducing the surface temperature of the planet and slowing global warming.

"This is the first time we have been able to accurately measure changes in global cloud height and, while the record is too short to be definitive, it provides just a hint that something quite important might be going on," explains lead researcher Professor Roger Davies.

He said longer-term monitoring will be required to determine the significance of the observation for global temperatures.

"We don't know exactly what causes the cloud heights to lower," Davies said, "but it must be due to a change in the circulation patterns that give rise to cloud formation at high altitude."
